 * &lt;p&gt;Wraps a collection of validation error responses and provides convenient functions for

 * 
 * &lt;p&gt;Usually this class does not need to be instantiated directly - instances are instead created
 * automatically when {@link Ext.data.Model#validate validate} on a model instance:&lt;/p&gt;
 * 
&lt;pre&gt;&lt;code&gt;
//validate some existing model instance - in this case it returned 2 failures messages
var errors = myModel.validate();

errors.length; //2
errors.getByField('name');  // [{field: 'name',  error: 'must be present'}]
errors.getByField('title'); // [{field: 'title', error: 'is too short'}]
&lt;/code&gt;&lt;/pre&gt;
